First Claim
Patent Images
1. A wood-type golf club head comprising:
- a body comprising a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown, wherein the body defines an interior cavity;
two or more weight ports formed in the body; and
at least two weights comprising at least one maximum weight having a maximum weight center of gravity and at least one minimum weight having a minimum weight center of gravity, each weight configured to be retained at least partially within one of the weight ports;
wherein a function, defined as a mass of the maximum weight minus a mass of a minimum weight multiplied by a vectorial distance between the maximum weight center of gravity and the minimum weight center of gravity, is between about 950 g·
mm and about 14,250 g·
mm.
